Abstract

Metal-containing polymers made with a range of metals, ligands, counterions and with different morphologies have been previously studied for their magnetic, opto-electronic and thermochromic properties. Presently, we are exploring the potential of transition metal-terpyridine-based complexes as polyelectrolytes for fuel cell membranes. A water soluble Ruthenium (II) bisterpyridine complex was covalently connected to a norbornene monomer and copolymerized with dycyclopentadiene (DCPD) via ring-opening metathesis polymerization (ROMP) to prepare a crosslinked membrane. Unlike traditional organic cations, the metal center in this membrane has two associated counterions. This system was also studied for its conductivity and chemical, thermal and mechanical stability. The conductivity, thermal stability and mechanical properties exhibited by these membranes were comparable to the conventional organic cations. These membranes demonstrated good alkaline stability and methanol tolerance. This study suggests that metal-ligand-based anionic exchange membranes (MLAEMs) represent an entirely new class of materials.
